The PCI-1737U/PCI-1739U is a 24/48-bit DI/O card with PCI bus. It provides
you with 24/48 bits of parallel digital input/output. It emulates
mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving
capability than the 8255. The I/O bits are divided into three 8-bit I/O
ports: A0, B0, and C0.( Six for PCI-1739U, A0, A1, B0, B1, C0, C1) You
can configure each port as either input or output via software.
The interrupt handling capability provides users the flexibility to generate
interrupt to a PC. 1-pin in the connector can output a digital signal simultaneously
with the card's generating an interrupt. (2-pin for PCI-1739U)
The other features give the PCI-1737U/PCI-1739U practical advantages
in an industrial setting. When the system is hot reset or power on, the I/O
port settings and output values of PCI-1737U/PCI-1739U will be determined
by switch.
